mlx4_core: maintain available field in bitmap allocator

2011-03-23T19:24:24+00:00

Add mlx4_bitmap_avail() to give the number of available resources. We want to
use this as a hint to whether to allocate a resources or not. This patch is
introduced to be used with allocation blue flame registers.

mlx4: use bitmap library

2010-08-28T22:37:04+00:00

Replace loops calling set_bit() and clear_bit() with bitmap_set() and
bitmap_clear().

Unlike loops calling set_bit() and clear_bit(), bitmap_set() and
bitmap_clear() are not atomic. But this is ok.
Because the bitmap operations are protected by bitmap->lock
except for initialization of the bitmap in mlx4_bitmap_init().

drivers/net: Convert unbounded kzalloc calls to kcalloc

2010-08-18T00:45:14+00:00

These changes may be slightly safer in some instances.

There are other kzalloc calls with a multiply, but those
calls are typically "small fixed #" * sizeof(some pointer)"
and those are not converted.

mlx4_core: Support multiple pre-reserved QP regions

2008-10-22T17:25:29+00:00

For ethernet support, we need to reserve QPs for the ethernet and
fibre channel driver.  The QPs are reserved at the end of the QP
table.  (This way we assure that they are aligned to their size)

We need to consider these reserved ranges in bitmap creation, so we
extend the mlx4 bitmap utility functions to allow reserved ranges at
both the bottom and the top of the range.

mlx4_core: Add QP range reservation support

2008-10-10T19:01:37+00:00

To allow allocating an aligned range of consecutive QP numbers, add an
interface to reserve an aligned range of QP numbers and have the QP
allocation function always take a QP number.

This will be used for RSS support in the mlx4_en Ethernet driver and
also potentially by IPoIB RSS support.

drivers/net/mlx4/alloc.c needs mm.h

2008-09-24T22:48:57+00:00

sparc32 allmodconfig with linux-next:

drivers/net/mlx4/alloc.c: In function 'mlx4_buf_alloc':
drivers/net/mlx4/alloc.c:164: error: 'PAGE_KERNEL' undeclared (first use in this function)
drivers/net/mlx4/alloc.c:164: error: (Each undeclared identifier is reported only once
drivers/net/mlx4/alloc.c:164: error: for each function it appears in.)

this is due to some header shuffle in linux-next.  I didn't look to see what
it was.  I'd sugges that this patch be merged ahead of a linux-next merge to
avoid bisection breaks.

We strictly only need asm/pgtable.h, but going direct to asm includes always
seems grubby.
